Multi-rotor unmanned aerial vehicle carbon tube damping and shock absorption undercarriage

Abstract

Belonging to the technical field of aircrafts, especially to the multi-rotor unmanned aerial vehicle field, the invention relates to a multi-rotor unmanned aerial vehicle carbon tube damping and shock absorption undercarriage, and aims to provide an undercarriage that can optimize multi-rotor unmanned aerial vehicle landing action by a pure mechanical way, correct abnormal landing state, protect whole vehicle and internal data security, and reduce the crash smashing risk. The undercarriage comprises a retracting mechanism, a shaft end, a damping shock absorber, a socket end, and a rubber protective pad. The damping shock absorber is mounted between the shaft end and the socket end, and is mounted in the socket end. The rubber protective pad is fixed at the socket end bottom, and the rubber protective pad can be directly mounted to and disassembled from the socket end in an interference fit way. And the damping shock absorber adopts pneumatic bumper. The undercarriage provided by the invention can absorb the moment pneumatic kinergety generated during unmanned aerial vehicle landing, realizes soft landing of each landing, and prolongs the service life of the whole vehicle.

Description

technical field [0001] The invention belongs to the field of aircraft technology, especially the field of multi-rotor UAV, and relates to a multi-rotor UAV carbon tube damping shock-absorbing landing gear, which aims to provide a purely mechanical way to optimize the landing action of multi-rotor UAV. Correct the abnormal landing state, protect the safety of the whole machine and internal data, and reduce the risk of crashing and bombing the landing gear. The invention can absorb the instantaneous motion energy generated when the drone lands, realizes a soft landing every time it lands, and prolongs the service life of the whole machine. Background technique [0002] The multi-rotor UAV has the characteristics of low cost, easy operation, high flexibility and ultra-low altitude flight. It can use the photography equipment on it to take pictures, obtain image data, and send the acquired image data back to the ground. . Multi-rotor drones have been widely used in aerial phot...

Problems solved by technology

[0003] The landing gear is the guarantee for the landing of the UAV. The shock absorption effect of the landing gear also affects the vibration amplitude of the UAV when it lands. Especially in the conditions where novices are not skilled in operation and the terrain environment of special missions is difficult to operate, the vibration If it is too large, it will cause crash and explosion, which not only affects the smooth completion of the task, but also causes a lot of economic losses

At present, the landing gear on the market mainly absorbs shocks by adding cushions, and none of them can achieve a soft landing. Therefore, the present invention has designed and developed a landing gear that can overcome the above-mentioned defects. Safety is particularly important
